I recommend using Infragistics or DevExpress. We have tried using both and both are good collections. Ultimately we landed on Infragistics but use only a few of their controls...primarily the grid. Telerik is also a good control collection and I know that we have a number of web developers that really love their AJAX controls.
There are other collections out there too: Janus, SyncFusion, etc. I like the people at SyncFusion and all of my encounters with them have been positive...but I am not as familiar with their collection.
Infragistics and DevExpress are safe bets and each collection has things about it that I like. The Infragistics grid is extremely deep and can pretty much do anything that you can come up with...the DevExpress good but I think that the Infragistics grid wins that competition overall. Infragistics has App Themes, but I prefer the way the DevExpress LookAndFeel work....though the DevExpress LookAndFeel became very slow on large forms. So we try not to use any 3rd party controls for the basic and use SF themes for our application and them bring in the outlier controls such as grids, etc. and use our themes with those controls by using all of the color properties to get what we want.
About the Report Shart-Shooter, I did not get that email. Do you have any idea when the sample will be available in your KB? or if they it will take a couple of week to release the KB and you can email me any sample during the week I would really appreciate it.
I am referring to our KB. We are going to be releasing a KB in April. I have not created the larger sample yet and I will not be able to get anything like this done this week. I have this on my to-do list and when I create the sample I will post it here on the forum so you can look at it.
